Kasu Udon: Where to Eat & What It Costs (Osaka)

Kasu udon is an udon dish from the Minami Kawachi area of Osaka, topped with abura kasu, beef intestine slowly fried at a low temperature. The abura kasu is light because the excess fat is rendered out, yet it releases a savory richness the more you chew. As it melts gently into the broth, it creates a flavor that is light but full of depth, and in recent years specialty shops have spread within the city.

Origins

The star of kasu udon, abura kasu, was born from a food culture rooted in the Minami Kawachi area, including Habikino and Fujiidera. As meat eating culture spread around Habikino in the Meiji era, abura kasu, a highly keepable ingredient made by frying beef small intestine to render out excess fat, is said to have come to be prized out of a spirit of not wasting food. Kasu udon, serving this as an udon topping, became beloved as a local flavor of Minami Kawachi and eventually became widely known through specialty shops in the city.
